The Thickness of Printing Paper List

Paper thickness, or caliper, is a critical physical property in printing and binding, directly impacting a project's final weight, feel, and functionality. This specification is distinct from paper weight (gsm), as different paper types with the same grammage can have varying thicknesses due to their composition and manufacturing process. The following reference tables provide precise thickness measurements in millimeters for a comprehensive range of paper stocks and boards.

These values serve as industry-standard references for print planning, allowing for accurate calculations for post-press processes like folding, binding, and packaging. Note that slight variations can occur between different paper mills and production batches.

There is also a growing emphasis on sustainable paper sourcing and the development of lighter-weight substrates that maintain structural integrity, supporting both environmental goals and operational efficiency.
